The seat warmer trick, Or why to always back up your dailies before the PA runs away with the flash drives.

The seat warmers in many cars are sometimes used to help keep take-out food warm on the way home (or to your destination). It works pretty good; you might be surprised.

The problem can occur when PA's put the pouch containing electronic media onto the same passenger seat that is cranked up (to hot), next to the food. Some of those seats use induction coils to generate heat; and that can result in magnetic waves or RF that can mess up the media. Depends on the make/model of the vehicle.

I have also heard of instances of seat warmers messing up loose credit cards or magnetic strip entry cards.
